Packet Dump
Failures in network can occurr by certain symptom. Each symptom can be traced to one
or more problems by using specific troubleshooting tools. The V5824G switch provides
the debug command to dump packet. Use debug commands only for problem isolation.
Do not use it to monitor normal network operation. The debug commands produce a large
amount of processor overhead.
The V5824G also provides debug command for Layer 3 routing protocols (BGP, OSPF,
RIP and PIM). If you want to debug about them, refer to the each configuration chapter.
